Written content, such as code for software programs and other written documents, often benefits from peer review. Software development, one example of content creation, may be overseen by managers such as project leads who spend many working hours reviewing code produced by their developers and appraising peer reviews provided by other developers, such as team members. Complex software projects can involve many developers in many locations, and reviewing code and code reviews in such a situation can be time-consuming and complicated for intermediate reviewers and project leads. A complicated reviewing process may result in a loss of productivity and poor content quality due to a possible lack of valuable peer and manager feedback and due to having no way of monitoring changes in quality of content and content reviews over time.
